Description

Technical Field

[0001] The utility model relates to the field of plant research equipment, in particular to a plant phenotype collection device. Background Art

[0002] Phenotypic collection is generally used to understand the growth and development of plants. Plant phenotypic measurement technology has become a key link in the research and application of monitoring and diagnosis of plant growth and appearance, assistance and screening of genetic breeding, and precision management of crops. By studying plant phenotypes, scientific guidance can be provided for plant breeding and pathological research. Plant phenotypic detection technology is an interdisciplinary subject covering biology, engineering technology, image recognition and analysis, and includes multiple key steps from plant image acquisition, image processing, phenotypic feature extraction, data analysis, and establishing the association between phenotypic data and genomic information.

[0003] The phenotypic acquisition equipment in the prior art is prone to shadows at the corners, which increases the difficulty of subsequent image processing and easily leads to inaccurate extracted data. In addition, the light source or shooting angle provided is relatively single, so the number of phenotypic parameters that can be extracted is also relatively limited. Therefore, how to provide the equipment with homogeneous lighting, background noise reduction and other capabilities is the key point to improve the equipment's ability to comprehensively reflect the phenotypic characteristics of the plant. Utility Model Content

[0004] In view of the above problems, the purpose of the utility model is to provide a plant phenotype collection device capable of homogenous illumination and background noise reduction.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The utility model provides a plant phenotype collection device, comprising:

[0007] A box body, wherein the box body is provided with a door for the plants to pass through;

[0008] A bird's-eye view camera, which is connected to the top of the box;

[0009] A side-shooting camera, which is arranged on one side of the box and moves up and down in a vertical direction under the action of a vertical driving device;

[0010] A background plate, the background plate is connected to the bottom of the box, and the background plate is arranged opposite to the side camera;

[0011] An adjustable storage table, wherein the adjustable plant table is connected at the center of the bottom of the box;

[0012] A light source is connected to the inner wall of the box.

[0013] Furthermore, the background plate is a black plate with an arc-shaped cross-section.

[0014] Furthermore, the light source includes a top light source and a side light source, the top light source is connected to the top of the box and is located on the side of the overhead camera; the side light source is connected to the side wall of the box and is located on the side of the side camera.

[0015] Furthermore, the light source is an integrated LED light board, and light beads emitting visible light, ultraviolet light or infrared light are evenly distributed on the integrated LED light board. The light source is an integrated LED light board, and visible light can be evenly dispersed with ultraviolet light or light beads of other wavelengths on the light board to provide diffuse light for plants. This provides a homogeneous lighting environment with reduced shadows for plants, and this lighting environment can better reflect the overall appearance of the plants. The images generated on this basis can better extract phenotypic data.

[0016] Furthermore, the visible light has a wavelength of 400-700nm.

[0017] Furthermore, the ultraviolet light has a wavelength of 200-380nm.

[0018] Furthermore, the near-infrared light has a wavelength of 700-1000nm.

[0019] Furthermore, the infrared light has a wavelength of 1000-2500nm.

[0020] Furthermore, the adjustable storage table includes a table top and a stepper motor, and the table top can rotate 360 ​​degrees when driven by the stepper motor.

[0021] Furthermore, the vertical driving device includes a guide rail, a motor and a ball screw. The side-shooting camera is connected to the ball screw and moves up and down along the guide rail driven by the motor. The guide rail is connected to the box.

[0022] Furthermore, the shooting center of the overhead camera is located on the central axis of the adjustable storage table.

[0023] Furthermore, tracks are provided at the upper and lower ends of the through door, and the through door is opened and closed by translation along the tracks.

[0024] Furthermore, there are two doors, namely an inlet door and an outlet door which are arranged opposite to each other.

[0025] Furthermore, it also includes a fill-in light mirror, which is installed on the inner wall of the door.

[0026] Furthermore, it also includes a power supply, which is arranged at the bottom of the box, and the motor, camera, light source and other devices that require power from the power supply can be connected to the power supply through wires.

[0027] The utility model adopts the above technical solution, which has the following advantages:

[0028] The arc-shaped background can minimize shadows or reflections. Due to its cornerless property, the common problem of insufficient lighting in corners can be avoided compared to a square background. The dark black color can absorb light, and will further ensure that when the black arc is used as the background, no shadows or reflections will be generated on the generated image. The diffuse light illumination brought by the evenly distributed lamp beads on the LED light board can also make the light source evenly distributed on the surface of the plant, thereby avoiding the generation of shadows, so that the overall picture of the plant can be better collected. In order to avoid shadows, using a dark black arc-shaped background can well avoid shadows, but the light intensity required for collecting images is higher than that of other light-colored backgrounds. In order to avoid overexposure caused by strong lighting, large-area mirrors are installed above the inner walls of the two doors of the equipment to fill in the light. This way of filling in the light can also make the light source of the box more diffuse through the reflection of the mirror, so that the imaging effect is more comprehensive. The side-shooting camera with adjustable height can adapt to different plant species and different stages of plant growth. Therefore, the utilization rate of the equipment is increased. In addition, the device of the utility model integrates the functions of overhead shooting and side shooting, so more phenotypic data can be extracted. The tabletop that can rotate 360° can also provide more collection angles for phenotypic collection. BRIEF DESCRIPTION OF THE DRAWINGS
